14.5.1 The "[...]" Syntax

14.5.1.1 Enclosing database identifiers

Database identifiers can be enclosed in the square bracket syntax as shown in the following examples.

[foo]=>#<SQL-IDENT "FOO">

This case corresponds to an unqualified SQL identifier as in:SELECT FOO FROM BAR.
[foo bar]=>#<SQL-IDENT "FOO.BAR">

This corresponds to a qualified SQL identifier as in:SELECT FOO.BAR FROM FOO
["foo" bar] =>#<SQL-IDENT "\"foo\".BAR">

This corresponds to a qualified SQL identifier with an aliased table name containing special characters as in:SELECT "foo".BAR FROM BAZ "foo".
[foo "bar"] =>#<SQL-IDENT FOO \"bar\">

This corresponds to an alias definition as in:
SELECT "bar".* FROM FOO "bar".
[foo :integer] =>#<SQL-IDENT "FOO" :INTEGER>

As above, but including a type coercion component.
[foo bar :integer] -->#<SQL-IDENT "FOO.BAR" :INTEGER>

As above, but includes a type coercion component.
["foo" bar :integer] -->#<SQL-IDENT "\"foo\".BAR" :INTEGER>

As above, but includes a type coercion component.
